The FRITSCH Variable Speed Rotor Mill PULVERISETTE 14

premium line offers impact, shearing and cutting commi-

nution in one instrument with a higher performance, better

cooling and is signifi cantly quieter than comparable instru-

ments. Its powerful motor is ideal for the particularly fast

comminution of soft to medium-hard, brittle as well as fi brous

materials and temperature-sensitive samples with an ex-

tremely fast sample throughput of up to 15 litres and more

per hour, depending on the material and parameter settings.

FRITSCH premium advantage: Pleasantly quiet ope-rationWe have incorporated special design features into the

FRITSCH PULVERISETTE 14 premium line to ensure that it is

considerably quieter than comparable instruments. Use of the

provided funnel lid and funnel insert reduces the noise level

even further. For a pleasantly quiet operation in accordance

with DIN EN.

FRITSCH premium advantage: Signifi cantly better cooling The strong airfl ow produced by the motor, an ingenious air

routing, as well as special cooling fi ns on the rotors further

intensify cooling. Your advantage: melting or sticking is

greatly reduced, even with temperature-sensitive samples.

The cooling function can easily be enhanced further by

utilizing the integrated option to connect an exhaust system

or a FRITSCH Cyclone separator.

FRITSCH premium line – the high-tech standard for the modern laboratory.e

FRITSCH premium advantage: High-speed motor with ceramic bearings The heavy-duty motor and especially durable ceramic bearings ensure a particularly high impact

and rotor speed with an extra powerful 22,000 rpm. Your advantage: fi ner results in shorter

times. And a long-term investment, which is defi nitely worth it.

6

AutoLOCK grinding chamber As soon as you have set the grinding parameters and started

the grinding, the AutoLOCK grinding chamber of the Variable

Speed Rotor Mill PULVERISETTE 14 premium line automatically

closes itself tightly and safely. A sensitive anti-clamping and

crushing protection ensures that the instrument lid blocks as

soon as it encounters an obstruction.

Intelligent controlThe integrated Intelligence-Safety-Control-System automatically

checks the grinding set‘s components – collecting vessel

with lid, rotor and labyrinth disk – for completeness and

correct insertion. Even the new FRITSCH Vibratory Feeder

LABORETTE 24 is detected by the programme. The grinding

starts only when all the parts are fully and correctly inserted

and the instrument‘s lid is properly locked. Your advantage:

absolutely safe operation with a complete safety lock.


Intelligent AutoLOCK grinding chamber enables incredibly simple operation

premium functionality for safe operation

Even particularly hard and fatty materials such as feed pellets can be easily comminuted with the PULVERISETTE 14 premium line.

As with all FRITSCH premium line instruments, the Variable Speed Rotor Mill PULVERISETTE 14 premium

line makes your work even easier, faster and safer. This is especially due to the new, intelligent AutoLOCK

grinding chamber and the integrated Intelligence-Safety-Control-System, which only allows the machine

to start once all the parts are correctly inserted.

FRITSCH premium advantage: The fi xation against twisting of the

sieve rings and collecting vessels

ensure less wear and even quieter,

vibration-free operation.

7

Well-designed touchscreen The Variable Speed Rotor Mill PULVERISETTE 14 premium line is operated via

the well-designed and ergonomically arranged touchscreen with a particularly

logical menu structure in different languages. Via the touchscreen you enter

the variable rotational speed and defi ne the grinding time using the minutes

and seconds timer. The integrated stopwatch function for time recording, e.g.

for new samples, is particularly practical. In addition as a system monitoring

safety feature, the instrument‘s power consumption and the system temper-

ature are displayed, and a warning is shown in case of overload.

Funnel for different grinding tasksEach PULVERISETTE 14 premium line is

equipped with a polyamide funnel with stain-

less steel insert e.g. for foodstuffs, a smaller

feeding funnel for fl exible adjustment to the

sample type and particle size, as well as a

noise-insulating funnel lid to guard against

splashes.

Flexible remote controlIf your PULVERISETTE 14 premium line is isolated for special grinding

tasks – e. g. in a glove box – it can be easily remotely controlled using a

separate computer. All system values can be read directly as well.

Practical: the spacious work surface for

labyrinth disk, rotor and sieve ring.

8


The well-conceived Clean Design of the Variable Speed Rotor Mill PULVERISETTE 14 premium line covers

all the areas, which make the cleaning of your mill as easy as possible: All the surfaces are designed

to be extremely dirt-resistant and easy to clean, and every surface which comes into contact with the

samples can be sterilised. And all the parts that need regular cleaning, like funnel, collecting vessel with

lid, rotor, sieve ring and labyrinth disk – each can be removed with a single motion without tools. Even

the lid of the instrument can be easily removed for cleaning.

Clean Design for fast cleaning

FRITSCH premium advantage: In the PULVERISETTE 14 premium line,

the grinding and electrical chambers are completely separated from each

other. Your advantage: The air in the grinding chamber does not come

into contact with the electronics and stays cooler – and the electronics

are protected from dust. A clever idea, which results in a longer service

life for your mill and increased safety with no faulty switching.

As a standard, the Variable Speed Rotor Mill PULVERISETTE 14 premium line is equipped with collecting

vessel and lid. In order to operate the mill, you must also order a rotor as well as a sieve ring – allowing

you to select your grinding tools according to your specifi c application.

The right accessory for each application

I M P A C T R O T O R S A N D S I E V E R I N G S

Inside the Variable Speed Rotor Mill, the sample is comminuted by impacting against the ribs of the impact

rotor, rotating at high speed and also sheared between the rotor teeth and the inserted sieve ring. The

extremely durable, low-wear, impact rotors with cooling fi ns and sieve rings with reinforced edges made

of the stainless steel of the PULVERISETE 14 premium line are suitable for all standard applications, for

comminution of medium-hard, soft, brittle, fi brous substances from lime to plants. To meet various grinding

tasks, impact rotors with 6, 12 and 24 ribs and cooling fi ns as well as sieve rings with trapezoidal or

round perforation from 0.08 mm to 6 mm with reinforced edges are available.

Diffi cult-to-mill or temperature-sensitive samples and plastics

The FRITSCH impact bar is the ideal solution for very gentle

grinding of especially heat-sensitive materials such as

powder coatings or plastics as well as for the smooth pre-

crushing and fi ne comminution of hard-brittle to soft, fatty

or samples with residual moisture. The impact bar acts as

a stator on which the material is additionally beaten. The

result: increased grinding performance for a particularly fast

and effi cient grinding that minimises the thermal load. The

corresponding impact rotor and a special sieve ring for the

impact bar must be ordered separately.

Heavy-metal- and iron-free grinding and sample prepa-ration according to RoHSFor heavy-metal- and iron-free grinding and sample

preparation according to RoHS, you can order your Variable

Speed Rotor Mill PULVERISETTE 14 premium line with a lid

made of pure titanium and collecting vessel PTFE-coated.

In addition, select a pure titanium impact rotor with cooling

fi ns:

Feed size < 15 mm

6-ribs impact rotor made of pure titanium

Feed size < 10 mm


Feed size < 5 mm


Then select the appropriate sieve ring with reinforced edges

made of pure titanium with a matching perforation for the

desired fi nal fi neness. The sieve rings are offered with trape-

zoidal or round perforation from 0.08 – 6 mm.

C U T T I N G W I T H T H E P U L V E R I S E T T E 1 4 premium line

Turn your PULVERISETTE 14 premium line into a Cutting Mill with just a few simple motions

for fast, effi cient pre-grinding of fi brous materials and plastics: Simply insert the cutting

rotor with cooling fi ns with the appropriate accessories such as the collecting vessel,

labyrinth disk and sieve ring – the materials are ground by cutting and shearing forces. The

PULVERISETTE 14 premium line will detect the labyrinth disk and automatically operate in

an optimised mode as a Cutting Mill with up to 10,000 rpm. The desired fi nal fi neness will

also be determined here by the selected sieve ring with trapezoidal or round perforation.

And the use of a FRITSCH Cyclone separator will further improve throughput and cooling.

Cool, clean and convenient: FRITSCH Cyclone separators for

sample exhaustion open up new possibilities, which would

otherwise be impossible. Their powerful airfl ow ensures

simple feeding and faster throughput. Due to faster operation

and the additional stronger cooling, the thermal load of the

sample materials is minimized, so that temperature-sensitive

samples can also be ground without any problems.

The powerful airfl ow enables the use of fi ner sieve rings to

achieve a higher fi nal fi neness – even for materials, which are

otherwise diffi cult to grind fi nely, such as electrostatically-

charged plastics or powder coatings. Especially convenient:

the ground sample is drawn directly into the screwed-on

sample glass, in which it can be transported, stored and

easily removed for analysis.

FRITSCH Cyclone separators

Optimal sample exhaust system: FRITSCH Cyclone separators

Especially convenient: direct exhaustion into the sample glass

Compact and powerful: the FRITSCH high-performance Cyclone separator made of stainless steel

13

FRITSCH high-performance Cyclone separator The compact FRITSCH high-performance Cyclone separator,

which is made completely out of stainless steel 304, is

particularly indispensable in the analytical sector and

the food and pharmaceutical industries. Due to its high

surface quality, it offers enhanced resistance to corrosive

media such as alkalis and acids, but particularly to media

containing chlorides – and is especially easy to clean with

a wide range of possible cleaning agents, without leaving

any residues. The Cyclone separator can also be fully

dismantled, meaning that it can be completely emptied,

fl ooded and sterilised. Your advantage: reliable protection

against cross-contamination.

FRITSCH Cyclone separator The larger FRITSCH Cyclone separator offers in addition to

all the above benefi ts such as faster throughput and reduced

thermal load, for all standard grinding tasks, an ultra-fi ne

HEPA dust fi lter, which keeps fi ne dust inside the Cyclone

separator.

Automatic feeding Directly controlled by and precisely matched to the mill, the

new FRITSCH Vibratory Feeder LABORETTE 24 always ensures

the correct feed rate – ideal for slowly feeding small or

smallest material quantities or for grinding larger quantities.

O U R S U G G E S T I O N : C R Y O G E N I C G R I N D I N GSamples which are diffi cult to grind or extremely temperature-sensitive

(e.g. plastics) can be embrittled with the addition of liquid nitrogen

and subsequently ground in the PULVERISETTE 14 premium line.
